12.2 Adiabatic panel

If the water flow that supplies the adiabatic panels is below a certain percentage threshold (parameter PA26) with
respect to the reference value calculated by the controller, only a warning is generated. In these cases, the adiabatic
panel remains active and still effective. The report is automatically resolved if the flow rises above the return
percentage, parameter PA27.
Wet flow control on adiabatic panels can be disabled by parameter PA25.
